Are You Dead? has surged to become China’s top paid App Store title, attracting iPhone users who live alone. The app, launched in May 2025, requires users to tap a large button every two days to confirm they are alive; failure to do so triggers an alert to a pre‑selected emergency contact. The concept taps into a projected 200 million one‑person households in China by 2030, explaining its rapid adoption among young urban residents.

Internationally, the same app, branded Demumu, ranks sixth in the U.S. paid app chart at $0.99. The name plays on the popular food‑delivery service E‑le‑ma, adding a cultural twist. Analysts suggest that Apple could respond by expanding its existing Check‑In feature in Messages to support regular health‑check prompts, potentially boosting user safety and engagement.

The trend highlights growing concerns over personal safety in densely populated cities and may influence future app‑store policies and developer strategies. Stakeholders include iPhone users, emergency‑contact services, and app‑store operators seeking to capitalize on the one‑person household market.
